The external antenna models (the AP 3600e and the AP 3500e) differ in appearance because the AP
3600ehasfewerantennaconnectorports,primarilyduetothedual‐bandantennasystem.

The AP 3600e has combined all the
antenna ports (dual‐band ) so that each antennaport can transmit
simultaneously oneachband; if the antennaportswerenot combined, this wouldhaverequiredeight
antennas. The AP 3600 has four transceivers (transmitter/receiver) radio ports per band for a total of
eighttransceivers,fourineachband.Thisadditional
